How do I find an immigration or naturalization record for an ancestor? Actually about 3 of them or so. I have a johann Heinrich Schultz whose immigration is listed as 1858 Scott Co., IA. Any tips? Where do I write to find this information? I also have a Sophia Hansen mother of Johann's wife Maria Dorthy (Mary) Hansen Schultz. Her father listed as Dudley "Dick" Hansen. A brother George. Any info appreciated. Katy Pitts
